Jacobian
Syntax
Jacobian(L:LIST):MAT
where L is a list of polynomials.
Summary
the Jacobian of a list of polynomials
Description
This function returns the Jacobian matrix of the polynomials in L
with respect to all the indeterminates of the current ring.
example
Use R ::= Q[x,y];
L := [x-y,x^2-y,x^3-y^2];
Jacobian(L);
Mat[
[1, -1],
[2x, -1],
[3x^2, -2y]
]
